The avocado is one of the holy grails of foods. You can make avocados into guacamole, add them to smoothies, and use them in sweet and savory dishes. And eating an avocado a day may be beneficial to both brain and eye health thanks to that popular bioactive, lutein. Study results showed that people who ate a whole avocado a day had better results on cognition tests than the control group, improving or maintaining their memory, processing speed, and attention levels.
Avocados are also full of healthy fats that feed the brain and preserve and protect cognitive function. And while eating a whole avocado a day might seem like a lot, the overall health benefits of this tasty fruit mean you should try to eat them when you can.
